This invention relates to refrigerating apparatus and more particularly to a. door for a refrigerator cabinet. v

An object of this invention is to provide a door adapted to be made of metal pans and provided with effective gasket construction for the purpose of insulating the pans from each ot-her.

Another object of this invention is to provide a. door of the pan type provided with effective gasket construction for sealing the door with relation to the refrigerator cabinet.

Further objects and advantages of the present invention will be apparent from the following description, reference being had to the accompanying drawing, wherein a preferred form of the present invent-ion is clearly shown.

In the drawing:

Fig. 2 is an enlarged view of a portion of Fi .1' y

Figf is a vertical cross sectional View of the door taken substantially along a plane corresponding to the line 3-3 of Fig. 2; and

Fig. 4 is an elevational view of a cabinet embodying features of this invention.

This invention relates to a refrigerator which may be of the mechanically cooled type which may comprise in general -a cabinet or refrigerator designated as 20. The cabinet or refrigerator may bey provided with a door jamb construction generally designated as 21 and with a door generally designated as 22. The cabinet may be provided with a food compartment lining 23 which may be insulated by insulation 24 an-d, if desired, the cabinet may be provided with an outer casing generally designated as 25. The door jamb 21 may be provided with a finishing strip 26 of wood or of moulded material which may be fastened to the door j amb 21 by means of screws 27. The finishing strip 26 may be provided with shoulders 28 and 29 which may be the portions of the refrigerator against which the gasket construction hereinafter to be described is adapted to bear.

The door 22 may be of the pan construction. Thus the door may include an inner pan 30 and an outer pan 31. The inner pan 30 may be provided with an edge' 32 which, if desired, may be continued by an inwardly directed flange 33. The outer pan 31 may be provided with an edge 34 which, if desired, may be continued as a flange 35. A rectangular frame 36 may be provided for the door. If desired, the rectangular door frame may be provided With an edge including a flanged offset 37. For convenience in construction, the frame may be made in tWo major parts. One part may include four Wooden pieces numbered 38 and 39 and another major part may include four other pieces made either of wood or moulded material and numbered 40.

The wooden pieces 38 and 39 may be assembled first in their relation to the pan 30. Thus the pieces 38 may be put in place with their notched construction engaging the flange 33. Thereafter the wooden pieces 39 may be placed in position with their ends between the pieces 38 and thus permanently spacing the pieces 38. The moulded or wooden pieces 40 may then be secured by means of screws 46 to the Wooden pieces 38 and 39. This construction provides the flanged offset 37 heretofore mentioned. Suitable insulation, which may be cork board or rock cork, may be inserted within the frame. This insulation `is designated asl 47.

The hinged construction 50 may be secured to the framework and preferabl to one of the strips 40 by means of some o the screws 46 and by additional screws 51, if necessary. The other portion of the hinge may be secured by screws 52 to the door jamb construction 21 undcr the strip 26. The outer pan 31 may then be secured to the frame of the door in any suitable manner as by screws along the flange 35, not shown.

It is thus seen that the frame is provided with an edge having a flanged offset 37 and that the two pans 30 and 31 are spaced so that there is a gap between the edges of the pans. A gasket construction may be placed 'the said nishing strip in this gap. A convenient construction may include a gasket 60 ad'acent the edge 320i the pan 30.v The nis ing stri 61 may be secured by screws 62 to the woo en stri s of the frame in such a manner as to loc the gasket 60 between the edge ofthe pan 30 and 61. If desired, a second gasket 63 may be placedfon the door. This gasket 63 may also'be locked, for instance, between the finishing strip 61 and the' flan ed offset 37. A convenient-method of so loc ing the gasket 63 may be by provid- By the construction heretofore described, a door is provided in which the outer parts are substantially all of metal, and in which the remaining exposed parts may, if desired, be made of moulded material or of well protected wood and thus no parts are exposed which may deteriorate readily. The gasket construction is readily replaceable should it be necessary to replace the gaskets due to the severe wear imposed upon them by the impact with the portions of the refrigerator. The gaskets may be replaced by the removing of the nishing strips 61 without disturbing the remaining door construction. The finishing strips 61, if desired, may be made of moulded material of the same character as the strips 40 and 26. A suitable material for these strips may be what is known in the trade as gilsonite or any other water proof material which may be suitably treated in order to render the same water proof and odor proof.

While the form of embodiment of the invention as herein disclosed, constitutes a pre- `the edge of the frame, a second metal pan on the other side of said frame with its edge adjacent the edge of said frame near said flanged offset, there being a gap between the edges of said pans, a gasket adapted to bear against a portion of the refrigerator, and a. finishing strip in said gap between said first named pan and said flanged offset adapted to lock said gasket in place between the edge of said first strip. Y

2. A refrigerator door comprising a substantiall rectangular frame havingan edge provide with a flanged offset, insulation within said frame, a metal pan on one side of said frame with its 'edge partly over the edge of the frame, a second metal pan on the other side of said framewith its edge adjacent the .edge of said frame near said flanged offset, there being a gap between the ed es of said pans, a pair of gaskets adapted to ar against portions of the refrigerator, and a finishing strip in said gap between the said first named pan and said flanged offset adapted to lock one of said gaskets between the edge of said first named an and said finishing strip, and adapted to ook the other named pan and said finishing of said gaskets between said flanged offset and said finishing strip.

3. A door for a refrigerator comprising a substantially rectangular frame, said frame including four square ended pieces with eX- ternal longitudinal notches, insulation within said frame, ametal pan on one side of said frame, said pan having inwardly directed edges partly over the edge of the frame andlocked in said notches by the frame, a second metal pan on the other side of said frame with its edge adjacent the edge of said frame, there being a gap between the edges of said pans, a gasket adapted to bear against a portion Vof the refrigerator, and a finishing strip in said notches adapted to lock said gasket in place between said finishing strip and the edge of one of said pans.

4. A door for a refrigerator comprising a substantially rectangular frame, said frame including four square ended pieces with exmetal pan on the other side of said framewith its edge adjacent the edge of said frame, there being a gap Ibetween the edges of said pans, a pair of gaskets adapted to bear against portions of `the refrigerator, and a finishing strip in said notches adapted to lock said gas ets in place, one of said gaskets being locked between theedge of one of said pans and said nishing strip and the other of said gaskets being locked between said frame and said finishing strip.

In testimony whereof I hereunto aiiix my signature.
